Thanks guys. I'm sure I'll learn a whole heck of a lot in the process.
Here is my situation. I'm away from home for the next 2 and a half weeks which of course is where the tractor is, so I can't do anything until then. SO what I'm trying to do is learn as much as I can so when I get home I can get to work on adding hydraulics. I want to figure out (with all you guys help of course) exactly WHAT I need and exactly HOW to do it. So far I think I have the valve all set, I'll buy the one previously posted, the 14gpm one.
I'm going to do it in two steps like Kennyd suggested. I'll buy the all the parts except the fittings and hoses, then mount the fittings and measure off everything I need, and order the hoses and connectors.
So far I can check the valve off the list. I guess now that I think about it there really aren't all that many parts when you don't count the hoses and connections?
So lets see, what will I need for the electric over hydraulic solenoid setup for the grapple? I think I'll go that route and plumb in a needle valve (wow I'm using all these technical terms now eh?

)
I'm not sure if I'll attempt to do that part of it myself or just spring for the WR Long setup. Does anyone know offhand a rough price of the kit? I think I remember reading around $500 but I'm not positive. Seems they include everything I need and that would nice.
